![]() ![]() Ham Radio Deluxe Digital Master (DM780) Settings. This from a friend who worked for a transformer and choke company in Cincinnati as a design engineer and has a MS in both physics and electronics. Just like a human copying CW, the JT65 decoder has a grey area in which it finds a solution but may. The rule was that if you could put your finger on the transformer and count 1001, 1002,1003 without screaming, then it was not too hot. Ham Radio Deluxe logs (with the HRD Logbook module) the digital modes of FT8, JT65A, and JT9 digital communicatons implemented by WSJT-X, via the JT-Alert. In other words, if they're cool when operating, you used too much iron and copper. The old axiom in transformers in power supply design used to be that if you run them hot, they are more economical copper-and-iron-wise. I don't like it though and prefer that a radio gets little more than a healthy warm. The person on the receiving end won't notice the difference in power levels, especially on digital modes where lower power is to me part of the interest in the system.īy the way, the Yaesu 65W 2M FM FT-2800M gets blazing hot after a few minutes use and outside of discomfort when touching, they continue to work. Therefore, I adjust the output power to 15W and have no problem with heat. ![]() ![]() Click to expand.I also have an X108G and have read how the radio heats up when cranked up full bore and using digital modes. ![]()
